If you want a precise digital tire pressure gauge with a bright LCD and lighted tip for quick checks, choose Slime 20017; if you need a durable 6-inch RV door holder to keep cargo hatches open securely, choose H. Bowes 2.
These two products solve completely different problems for vehicle owners. One is an essential tool for maintaining tire health and fuel efficiency, while the other is a mechanical hardware piece for keeping trailer doors or camper hatches propped up. Comparing them directly is like comparing a screwdriver to a wrench, but understanding their specific roles helps you buy the right part without hesitation. Whether you are prepping your car for a road trip or securing your delivery van's rear hatch, getting the spec right matters more than anything else.
• Slime 20017: Offers a bright LCD screen and a lighted tip for easy nighttime reading, but it is strictly a measurement tool with no moving parts to mount.
• H. Bowes 2: Features a robust T-style design made of durable plastic to hold heavy doors, though it requires separate mounting screws that are not included in the box.
• Best for: Choose Slime 20017 if you need to monitor PSI, kPa, or bar for safety and gas mileage; pick H. Bowes 2 if you need to replace a broken latch on an RV, trailer, or cargo hatch.
The Slime 20017 is designed for drivers who need speed and clarity when checking their tires. The standout feature here is the bright LCD screen, which eliminates the squinting required by analog gauges. You get immediate feedback on whether your tires are properly inflated, a critical step for safety. The device also includes a lighted tip, meaning you can check your pressures late at night or in dimly lit garages without needing a flashlight. This makes it a practical addition to any emergency kit or roadside repair bag.
This tool measures in psi, kPa, and bar, offering flexibility regardless of your preferred unit system. It features an automatic shut-off function to preserve battery life, paired with long-lasting, replaceable batteries. If you drive frequently, this small investment in maintenance pays off through better fuel economy and longer tire life.
You should buy the Slime 20017 if you prioritize convenience and accuracy in tire maintenance. It is ideal for daily commuters, road trippers, and fleet managers who need to ensure their vehicles are running efficiently. However, if you are looking for a heavy-duty mechanical component to attach to a vehicle body, this product is not for you. It is purely a handheld diagnostic tool. Skip this if you do not own a vehicle with standard pneumatic tires or if you already have a high-end setup that does not require manual pressure checks.

The H. Bowes 2 Pack is built for one specific job: holding doors open. These are OEM T-Style RV door holders, measuring 6 inches in arm length. They are constructed from durable plastic, which suggests they are lightweight yet strong enough to handle the tension of a swinging hatch. The black finish is designed to blend in with most RVs, campers, and cargo trailers. Because they are a direct replacement for many OEM installs, you likely won't need to modify your existing mounting holes if your current holder has failed.
What makes this product stand out is the quantity. You receive two units in the package, which is useful if you are replacing both sides of a dual-door setup or keeping a spare on hand for future wear. The 6-inch arm length provides a solid range for opening cargo hatches wide enough to load gear comfortably. Unlike the Slime gauge, this item is a static fixture once installed. It relies on its physical structure to stay in place, provided you secure it correctly.
You need the H. Bowes 2 if you are dealing with a broken door catch on a recreational vehicle or a utility trailer. It is perfect for anyone who wants to keep a hatch open hands-free while loading supplies or cleaning the interior. However, be aware that the mounting screws are not included. You will need to source the correct fasteners separately based on your specific vehicle model. If you are looking for a magnetic holder or a hydraulic strut instead of a simple T-style latch, this plastic option might not meet your needs. It is a straightforward mechanical fix for a common annoyance.
• Best for precision reading: Slime 20017 wins with its digital display and multiple unit options (psi, kPa, bar).
• Best for physical holding: H. Bowes 2 is the only choice for mechanically securing a door or hatch in an open position.
• Best for low-light conditions: Slime 20017 features a dedicated lighted tip for visibility in the dark.
• Best for durability in weather: H. Bowes 2 uses durable plastic designed to withstand outdoor exposure as a permanent fixture.

• Best for multi-unit needs: H. Bowes 2 comes as a 2-pack, making it better value for double-door setups.
• Best for portability: Slime 20017 is small and handheld, easily fitting in a glove compartment.
I would buy the Slime 20017 if my priority was maintaining my vehicle's performance and safety standards. The ability to see readings clearly at night and track fuel efficiency makes it an indispensable tool for any driver. On the other hand, I would choose the H. Bowes 2 immediately if my RV door catch broke down and left me unable to access my cargo. For food delivery scenarios where reliability is key, having a working door holder ensures you can unload quickly, while accurate tire pressure prevents breakdowns on the road. Ultimately, these tools serve different masters, but knowing exactly what each one does allows you to make the right call for your specific situation.
Yes, the Slime 20017 measures from 5 to 150 PSI, which covers the typical pressure ranges for motorcycles, cars, and trucks, and it displays readings in psi, kPa, and bar.
No, the product information explicitly states that mounting screws are not included, so you must provide your own fasteners compatible with your specific RV or trailer model.
The holder is constructed of durable plastic and is designed as a direct replacement for OEM T-style latches, suggesting it handles standard cargo hatch weights effectively.
